NIT

If you are getting reputed NITs then go for JoSAA counselling. NIT colleges meet standards of some of the IITs. So it is up to you if you are getting NIT with your JEE Mains rank or not. EAMCET shall be your 2nd choice.

Admission in NITs is given through JEE Mains marks. If you have qualified JEE Mains then only you will get admission in NITs.
